The MVP2 is very good for the money. Shortly, though, the iStick will be out and it seems to be better. I have been using MVP2s for awhile with Protank 2s. Pretty simple.
One thing that I noticed that was not mentioned is that I only use one juice with one coil. I just don't like to get flavors mixed together. Sooo, I have a bunch of Protank 2s with different flavors running.
Currently, a friend is starting out so I am passing some PT2s on to him and I am getting Aspire Nautilus tanks. I tried one and it was good. Cost a bit more, though.
I am figuring to be adding an iStick and Nautiluses for Christmas. I still like to tinker with my Kayfuns, though. Also, I am going to lower my ohms for more flavor, too.
Its just where I am going for getting better flavor.
Just thought to pass on. Hope helps.
